Application filed July 29, 1909. Serial No. 510,281.

To GN tric-om if may concern:

Be ity known that i, JAMES Fnnniziiicit lnriziis. n citizen of the TUnited States, residing :it liigonier, .in the county of est more-hind und State of Pennsylvania, here invented certain new :ind useful improvements in folie-Oron Doors, of which the foilowing is a syveciiicntion.

This invention relates to doors, partienlarlr colte oven doors. Y

Une object ot' the invention is to provide 'i coke or other oven door whose metallic parts are not subjected to the direct heut of the furnace, so as to obviute loosening 'of the puits :ind to maintain rigidity.

Another object of the invention is to prf vide double or sectional doors for coke or other ovens which are not supported directly upon their hinges when in operative position. whereby the doors and their mountings are not under strain and h v virtue of which warping of the doors is obviated. because the doors setr on their own bases and thereto: sustain their own weight.

Another object ot the invention resides in the provision of :i door for col/ie. or other ovens tintiod-"ing such characteristics that and its inountings :tre spaced from the oren so that the oren may be. relined when oceasion requires Withoutl removing the door :ind its niountings from the furnace.

Another object of the invention is to provide :i coke or other oren door composed preferably of upper and lower sections hai'- ing niountings embodying parts operable to raise them, said parts operating to permit a free graritating swinging of the doors to their operative positions.

It is still further designed to provide a door for coke or other ovens composed of ai plurality of silica or other refractory bricks which are bound together by metallic eienients that. are exposed tothe air, and not to the heat. of the iurnace, Whether the door be in operative or inoperative position.

[A A still further object. of the invention re sides 'in the provision of a refractory door for eolie or other ovens which is so mounted y that itnmy be employed as a closure. `for one end of u coke oven or for the sanie end of an adjacent oren or be s0 positioned at the same end 'of the adjacent oven that its partswliich have become heated, as the resultof being oren, that a person will not he liable to seriously burn himself in the event of coming accidentally into contact. with the door when open. Furthermore by turning the heated side tower-:l the adjacent oven it. does notJ allow the temperature of the brick to change too rapidly, theneby giving much longer life to the door. Y

With the above and other objects in view, the present invention consists; in the conibination and arrangement of parts hereinafter more fully described, illustrated inthe accompanying drawings, and particularly pointed out. in the appended claims, it. being understood that. changes ina-y be made in the forni, proportion, size and minor details without departing from the spirit or sacritcing tiny of the advantages of the invention.

ln the drawiiigs:h`igure 1 is u front door prior to swinging the doors outwardly.

Fig. -l illustrates the position of the upper door when swung out of cooperative relation with the lower door and into position in the adjacent oven. Fig. 5 is a. top plan View. Fig. 6 is n transverse sectional view through one of the doors. Fig. 7 is a transverse set-.tion through u door showing u modified form of door and the metallic members connected thereto.

tferring now more particularly to the accompanying drawings, the reference characters 1 2 und l indicate u group of parallel coke ovens which are open at both eiids, as usuali and whose openings each include an arch 4. side facing walls :'i and a hearth G.

'The charm-ters a and b indicate upper and lower doors, euch composed of a plurality of silica or other refractory bricks or the like 7. und preferablyv` iinperforzitc. Euch brick is preferably provided with a projecting portion 8 on its outer face, so that when the plurality of bricks 7 of each door are assembled, the projectingr portions 8 form 1 a shoulder 9 to receive the upper and lower placed in operative position in a Working metallic o r other straps 10 and 11, respectively. These straps embrace said shoulder and have their ends deflected to Vform meeting faces l2 anti 13, respectively, through which nre puseed the holtsl l, huring nut:v 13 opernlile thereon, so that titel straps 1t) :incl ll may 'ne hound tightly'upon the. shoulder J of the doors to hind the bricks tightly together. The metallic straps 10 :intl il :intl their securing uref-ins :ire secured adjacent the outer face of the doors without any part thereof projecting through the doors so that. the metallic parts are not, subjected in any wny to the direct heat of the oren when the doors are closed, linut ure expobtetl nlin'olutely to the nir when the doom are in closed position.

The upper :intl lower metallic straps 1G and ll ure provided with the otuwzirtllydirected perforated enre'. 16 und l?, rffipectively, adjacent which are (imposed the 1S and 19, respectively, or :i hnlt Fig. (l).

The hinges 2G und 2T of the upper :unl lower doors (L and b. respectively, :ire provided with other urine .29 unal 3G, which l orutetl lo enihruce the. supporting u. n or hinge pintleI Ill,whorfeioweremi is nnirccl und lttctl in a rectangular opening er in :my other suitable manner 'ecuretl in u concrete or other 152 ntljuet it the wullf d the ovens :and preferably intermediate :nljueenl orennv und in spaced relation to the walls thereof for the support of the hingen. there being u l/Slnipetl or other forni of inzicht-t 33 secured in :my s'uituhle manner within the Walls of the oven strutture or swuretl in. any suitable manner to the outer uce ot' the walls of the structure for the poort of the upper end ot' the enpporting noz-ight or pintl'e 3l.

The pintle Ill hun tixetlly secured thereto in nnysuitnhle ninnncr the upper und lower Canis 34 unil C55, which :1re tlifposerl in hput'eil relation to euch other :intl whoxt ruin fin-es 36 cooper-.ite with the cunt zn'e IJ formed on euch of the rotuiililc upper :intl lower cams 3S'untl 39, repectivelv. euch of which latter has one or more sociietn i0 into which may be insel-teil u roll or other implement (not shown), to permit of iurninf ot'- the y i utinmphere. that neither the strnpS nor l the-hinger; cnn :it any time become unduly heutetl, unil thereby rendered so hot as to b'ernlusly injure persons or to contract and expand zo such proportions as to result in sepzaration :if the metallic parts from the (lo-'ir or otherwise to become loose with relation to the door 3nd other cooperating parts. Ae shown iu Fig. l, the doors ure closed at :wen .Z, with the lower door restin drec-thv 'upon the heart-h of the oven an the upper'door testing directly upon the upper edge or" the lower door. hy virtue of which, the hit-igea'. are relieved of any strain because the .Y cnrs nre onljiy steudietl thereby and not ted hy the hinges when the doors are e it is the custom to mud the cracks f. en the doors and between the edges thereof und the walls of the oven. To open the doors., a roti or other suitable implement (not Shown) disposed in one of the Sockets nl of the upper com i8 and the latter rotated to cause its cam ffice to richI upon the cunt uce of the cum 34. This operation .unes the cuni 3S to move upwardly on the i hub? pintle 3l. und being disposed beneath l the upper hinge@ causes n slightelevation l of lutter, ns shown in Fig. 3, when the v thin. :ice thereof which hns been suhjectcel to th hentof the oven so turned townrti oren l that the metallic straps i() und ll nznl the other nieiullic pui-ts, including:r the hingen. ure. still turned` uwuy from the structure au that nt no time ure :my of the metallic pnl-ts eznhjeetefl to the direct. heut oi' the ovens. while that. surfuce of the doors which lumA become heutetl is' generally turned townrtl the structure. lf desired, the peculiar link connection il() hei wcenthe hinge inni door will permit the n'ietullic parts of the door to heturnetl towuril the :nljucent oren. ll'hcn the upper door i5 thrown outwardly uwuy from the oven Q, it muy .swing upon the hinge pintle 2l of the link 3U while' the link 20111115 swingl upon the hinge pintle S to permit the door to he swung entirely urouinl. us shown in Firs. und 5. Thus the upper floor lubA u tloiilile `winging movementv .so that, while the hing-e of the upper l lnor i.-;suh. tunti:1lly parallel therewith. when l the door is in operative position, the tloor muy be `swung, if desired, into engagement :it one einl with its hinge, as muy be apparl'eut hy the full lines in Fig. 5.

The lower door :intl its hinge'einhodies 'the saine charucteristic :intl is preferably of y i i the saine construction, save that. itmay differ l has a double swinging movement.s upon its slightly in shape at its upper edge and be smaller or larger, as may lie desired. Thus by operatinfr the lower cam 139 in the same manner as the cam 38, the lower door b may be raised and swung open and closed the same as door a..

By virtue of the cam mechanisms, the upr and wer doors may 'ne easily closed,

cause the cam mechanisms rovide for a free and easy return swing o the doors to their operative positions, :Ls will be understood.

In Fig. 7 there is shown a modied form of door, the onlv diteren between thel modified form and the forti rst. described, however, residing in the Drei acting portions S having their edges beveled tov orm a dove-tailed shoulder 40' adatited to receive the beveled or dove-tailed lces iof the upper and lower straps 18 and il.

lt will be seenl that, the supporting neans is disposed in spaced relation to the walls of the ovens, by virtue of `which the linings 5 at the sides of the oven, as well as the hearth and arch thereof may be repaired, if necessary, without removing the doors or their sup orting means from the structure. It will a so be seen that surfaces of the doors and their aggroupmenrs. which are not subjected to the direct heat of the oven, may be ex sed to the atmosphere whether the doors in open or clcfi position. It will also be seen that the litiges proper are spaced from the doors so hat at no time do they become unduly heated, It will also be apparent that'the iron Ys of the device are not subjected to direct heat of the furnace, and when subjected to any heat atall, it is only whenthe doors are at rest; hence warping is obviated because doom, when subjected to heat, are not under strain.
